Adding user agent LODSPeaKr

* Back to "first" instead of "f" to increase readability
* default views and models are now rdfs:Resource
* 'use_external_uris' renamed to 'mirror_external_uris' to increase
readability
* When mirroring URIs, LODSPeaKr will include two triples using
(owl:sameAs and  con:prerredUri) from mirrored URI to original one

Fixed importing params (remoevd extra /)

TODO: include app-level params, such as root, as well as provenance
data (where was this application originated, at which time it was
collected, etc.)
